Addition Polymerisation

Question 1

what is a polymer made by

Answer 1

joining thousands of small identical molecules (monomers)

Question 2

is addition polymerisation by a alkane or alkene

Answer 2

alkene

Question 3

in addition polymers, the repeating unit has the same atoms as the monomer- why

Answer 3

because no other molecule is formed in the reaction

Question 4

how is the name of a polymer formed

Answer 4

the name of the polymer is the word ‘poly’ followed by the name of the monomer

Question 5

whats good about addition polymerisation

Answer 5

100% atom economy (no other products)

Question 6

features of addition polymerisation

Answer 6

• 100% atom economy
• no other products
• from alkenes

Question 7

features of condensation polymerisation

Answer 7

• forms another small molecule (water of HCl)
• starts with diol and dicarboxylic acid
• 2 reactants
• polyester
• not hydrocarbon as it contains oxygen

Question 8

diacyl

Answer 8

• Condensation polymerisation that produces hydrogen chloride (HCl) gas as a by-product
• typically involves reactions between diacyl chlorides (or acid chlorides) and either diols or diamines.
